BELT-FASTENER.

Specification of Letters Patent.

Patented June 22, 1909.

Application filed December 27, 1907. Serial No. 408,252.

To all whom it may concern:

Be it known that I, ALFRED ERNEST SLIP- PER, of Kokiri, Greymouth, NewZealand, sawmiller, have invented certain new and useful Improvements inBelt-Fasteners, of which the following is a specification.

This invention relates to belt fasteners of the kind in which the beltends are secured between side plates pivoted to end plates or to a framewith or without a central cross bar extending between the belt ends.

Belt fasteners of the kind referred to have been devised in which theside plates are made with faces triangular in cross section, the sharpangular edges being opposed to the belt ends, and no cross bar beingused; belt fasteners of the kind referred to have also been devised inwhich the side plates are made with curved faces opposed to belt endseither no cross bar being used, or a cross bar used extending betweenthe belt ends above the gripping portions of the side plates; but suchbelt fasteners are not my invention.

Accordin to my invention two flat sided plates are pivotally secured toend plates by pivots on and above the center of the side plates, a fiatcentral plate provided with pivots at the ends of its upper edge beingadapted to lie between the belt ends, so as to separate them, with thepivots resting on central notched portions in the end plates, ashereinafter set forth and pointed out in the claim.

It will be seen that in my invention the ends of the belt are not held,as in belt fasteners of similar type heretofore devised, by the ends ofthe belt being pressed together by the side plates, but that in myinvention one end of the belt is gripped between the inner face of onepivoted fiat-sided plate and one face of the pivoted fiat central plate,and the other end of the belt is gripped between the inner face of theother pivoted flat-sided plate and the other face of the pivoted fiatcentral plate. This arrangement prevents the slipping of the belt endswhich is likely' when they are pressed together, and the flat shape ofthe plates insures a smooth grip, while their pivotal relation to oneanother causes the whole of the parts to work smoothly togetherwhichever way the strain comes.

My invention is illustrated in the accompanying drawings in which thesame numerals of reference indicate the same parts and, Figure 1 is aplan of the belt fastener, Fig. 2'is a side view of the same. Fig. 3 isan end view of the same. Fig. 1 is a perspective view of the same withthe central plate removed, Fig. 5 is an end view of the belt fastener inposition on a belt. Fig. 6 is a perspective view of the central plate.

According to this invention there are two short vertical end plates (1)(2) having the central parts of their upper edges extending upwardly,and having notches (3) (4 formed thereon respectively. Two flat-sidedplates (5) (6) lie between the end plates (1) (2) and are pivotallysecured thereto by pivots (7) (8) formed integral with, and above thecenter of the side plates (5) (6) and passed through holes formed in theend plates and burred over to hold them in position. The side plates (5)(6) are rounded at their edges so as not to cut the belt when strainedand their upper ends (9) are corrugated or roughened to grip the beltWell. The ends (10) (11) of the belt to be fastened are passed upbetween the side plates (5) (6) and pulled through a short distance orsufiicient to tighten the belt for the purpose in view. The central fiatplate (12) is then dropped between the two belt ends (10) (11) so thatit lies between them being supported by integral pivots (13) (14) at itsends respectively resting in the notches (3) 1) in the end plates (1)(2). The central flat plate (12) is roughened or corrugated on bothsides see Fig. 6 to assist in effecting a tight grip. hen the straincomes on the belt the pivoted flat sided plates (5) (6) jam the beltends (10) (11) against the flat central plate (13) which separates thebelt ends these being held securely as shown in Fig. 5.

Having now described my invention what I claim as new and desire tosecure by Letters Patent is A belt fastener comprising two end plateshaving the central part of their upper edges extending upwardly each ofsaid extending portions having a notch therein, two flat side platespivotally secured to the end plates, by

pivots integral with and above the center of the side plates, and a flatcentral plate lying between said side plates and having pivots at itsupper edge said pivots Working in the notches in the extended portions,the belt ends being gripped between the inner faces of said side platesand the faces of said flat entral plate substantially as described.

In witness whereof I have hereunto set my hand 1n presence of twowltnesses.
